This test mainly explains the importance of the tread pattern to the tire noise. It is well known that the pattern of the tire is mainly used for rain drainage, and the air gap between the patterns is also the main source of tire noise, which is air compression and The inevitable result of the sudden release is that the tires with no pattern at all are in the test car. We don’t feel any noise in the car, it’s very quiet, and this “skin tire” is also unusually gripping, so the car is usually dry to use tires without patterns, and its fancy Obviously the effect of grip. However, in daily driving, under various climatic conditions, it is still necessary to have a tire with a drainage function, otherwise it will be very dangerous.
